CONSUMING SAP NETWEAVER GATEWAY SERVICES

FROM .NET APPLICATIONS

SAP NetWeaver Gateway technology provides a simple way to interact with SAP applications through

variety of devices, environments and platforms based on market standards. The framework enables

development of innovative, people-centric solutions that bring the power of SAP business software into

new experiences, such as: social networking and collaboration environments; mobile and tablet devices;

and rich internet applications. The framework supports rapid innovation while ensuring security, integrity,

management and optimized maintenance of the core SAP systems. Completely flexible, the software offers

connectivity to SAP applications using any programming language or model without the need for SAP

knowledge by taking advantage of REST services and OData/ATOM protocols.

This guide provides information on how to consume SAP NetWeaver Gateway services from .NET

applications based on the following scenario:

The user wants to fly from New York to San Francisco.

He goes online and searches for the different flights available. He enters his search parameters: city of

origin, destination city, departure date, and arrival date (Function Import).

From the SAP NetWeaver Gateway, he receives the information for the option(s) that meet(s) his search

parameters (Get Function).

He can now select the one that suits him the most and book his flight (Create Function).

The links to access the service document and metadata document are provided the in table below.

Service Document

http://<Gateway_host>:<Gateway_port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/

Metadata Document

http://<Gateway_host>:<Gateway_port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/ $metadata?$format=xml

Each service URL should contain the following information:

Gateway host

Port

SAP Client – no need to specify client if connecting to the default client.

Example:

http://<Gateway_Host>:<Gateway_Port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT?sap-client=100

To obtain information on the selected service (its properties, function imports, associations, etc.), refer to

Appendix 1, were we show the Metadata description of the RMTSAMPLEFLIGHT service.

To view the code snippets in a format that can be copied into new code, refer to Appendix 2.

The Flight service contains the following collections:

Collection URL

FlightCollection (list of flights)

http://<Gateway_host>:<Gateway_port>/sap/opu/ sdata/iwfnd/RMTSAMPLEFLIGHT/FlightCollection

CarrierCollection (list of carriers http://<Gateway_host>:<Gateway_port>/sap/opu/ sdata/iwfnd/RMTSAMPLEFLIGHT/CarrierCollection

BookingsCollection (list of Bookings) http://<Gateway_host>:<Gateway_port>/sap/opu/ sdata/iwfnd/RMTSAMPLEFLIGHT/BookingCollection

The operation GetAvailableFlights on FlightCollection is used to get a list of flights. The following is the URL

for the same:

http://<Gateway_host>:<Gateway_port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/GetAvailableFlights?

Each collection supports some or all of the operations listed below. The table below provides the list of

operations supported and the methods that each of this operations map to respectively:

Operation Method

Create HTTP POST

Read GET

Update PUT

Delete DELETE

Prerequisites

The following tools are required for developing a .NET application:

Software Version

SAP NetWeaver Gateway 2.0

.NET .NET Framework 4.0

Make sure you have performed the following:

Add proxies for the relevant service to your .NET project as described in the "SAP NetWeaver Gateway

developer tool for Visual Studio" documentation. You can find the documentation at SCN.

Add a reference to the System.Web.dll which is part of the 4.0 .NET Framework.

Import the following namespaces:

using RMTSAMPLEFLIGHT;

using System.Net;

using System.Web;

using System.Collections.Specialized;

Building a .NET Application

Function Import Example

To get a list of the available flights, based on filter criteria, trigger a “GetAvailableFlights” function import

with cityFrom, cityTo, fromDate and toDate parameters. The response will contain a list of flights that meet

the criteria.

Note: For more information on Function Import (also called Service Operation), refer to OData

documentation at http://www.odata.org/developers/protocols/uri-conventions under the Addressing

Service Operations section.

Refer to the code snippet below for details on how to do it from a .NET application:

1. Use the following method for executing a Function Import that returns a collection of flights.

private static void GetAvailableFlights() {

2. Connect to the desired service.

string serviceUrl = "http://<Gateway_Host>:<Gateway_Port>/sap/opu/sdata/iwfnd/RMTSAMPLEFLIGHT/"; RMTSAMPLEFLIGHT.RMTSAMPLEFLIGHT service = new RMTSAMPLEFLIGHT.RMTSAMPLEFLIGHT(new Uri(serviceUrl));

3. Enter the service credentials.

service.Credentials = new NetworkCredential(username, password);

4. Create the Function Import.

a) Enter the name for the Function Import you want to call.

string functionImportName = "GetAvailableFlights";

b) Set the values for all Function Import parameters in the NameValueCollection object.

NameValueCollection nameValueCollection = HttpUtility.ParseQueryString(String.Empty); nameValueCollection["cityfrom"] = "NEW YORK"; nameValueCollection["cityto"] = "SAN FRANCISCO";

http://www.sdn.sap.com/irj/scn/index?rid=/webcontent/uuid/a09fe802-c162-2e10-d59a-be4a4f27c49b#section10

http://www.odata.org/developers/protocols/uri-conventions

Copyright/Trademark

nameValueCollection["fromdate"] = "20110727"; nameValueCollection["todate"] = "20110728";

string relativeUri = functionImportName + "?" + string.Join("&", Array.ConvertAll(nameValueCollection.AllKeys, key => string.Format("{0}={1}", HttpUtility.UrlEncode(key), HttpUtility.UrlEncode(nameValueCollection[key])))); Uri uri = new Uri(relativeUri, UriKind.Relative);

c) Execute the call to the Function Import and save the result.

var result = service.Execute<Flight>(uri);

d) Iterate all objects in the result obtained above.

foreach (Flight flight in result) {

Console.WriteLine("---------------------------------------"); Console.WriteLine("Flight carrier = " + flight.carrid); Console.WriteLine("Flight price = " + flight.PRICE); Console.WriteLine("Flight seatmax = " + flight.SEATSMAX);

}

}

Create Example

To book a Flight, trigger HTTP POST method on the Booking Collection (with the Booking details in the

request body). Check for the HTTP response code. If the response code is 201, then the HTTP-POST is

successful. The response contains the newly created Booking ID in the bookid field, as well as the entire

information that was part of the request body.

Refer to the code snippet below for details on how to invoke a create request from a .NET application:

1. Use the following method for booking a flight.

private static void CreateFlightBooking() {

2. Create the new Booking item.

Booking booking = new Booking() {

carrid = "AA", connid = "0017", fldate = "2011-07-27T00:00:00", bookid = String.Empty, CUSTOMID = "00004617", CUSTTYPE = "P", WUNIT = "KG", LUGGWEIGHT = (Decimal)14.4000, CLASS = "Y", FORCURAM = (Decimal)879.82, FORCURKEY = "USD", LOCCURAM = (Decimal)803.58, LOCCURKEY = "USD", ORDER_DATE = "2011-05-22T00:00:00", COUNTER = "00000000", AGENCYNUM = "00000325", PASSNAME = "Joe Smith", PASSFORM = "1234567", PASSBIRTH = "1990-10-10T00:00:00",

};





5. Add the new Booking item to the service. Note: The changes are made only in the client side – the service is not aware of these changes.

service.AddToBookingCollection(booking);

6. Save all changes made to the service.

service.SaveChanges();

Copyright/Trademark

Creation of Request Body for Create Method:

The request body can be easily created by looking at the tags in the collection’s metadata. For example, the

metadata for Booking Collection provides information about the various fields (tags) that are needed for

creating a booking:

Authentication Using X.509 Certificate

In the code snippets above, the requests sent to the service use Basic Authentication.

If X.509 Certificate Authentication is needed, the X.509 Client Certificate should be attached to any request

sent to the service

Prerequisites

Make sure you have performed the following procedures:

Store the X.509 Client Certificate in the X509 Store under the Current User section.

The X509 Store can be accessed in Windows using the Certificates snap-in available in the Microsoft

Management Console (MMC). For further information, refer to http://msdn.microsoft.com/en-

us/library/ms788967.aspx

Obtaining the Client Certificate from the X509 Store

Follow the procedure below to retrieve a user Client Certificate from the X509 Store in a computer running

Windows operating system.

1. In the method below, enter the subject of the certificate.

public static X509Certificate2 GetCertificateFromX509Store(string subject) {

2. Select My Certificate Store and the Current User section in the store.

X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser); store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);

3. Look for the certificate with a specific subject.

X509Certificate2Collection certArr = store.Certificates.Find(X509FindType.FindBySubjectDistinguishedName, subject, true);

store.Close(); if (certArr.Count > 0) { X509Certificate2 cert = certArr[0]; if (cert.HasPrivateKey) {

4. Return the certificate with its private key.

return cert; } else { throw new CryptographicException("No private key found"); } } else { throw new CryptographicException("No certificate found"); } }

http://msdn.microsoft.com/en-us/library/ms788967.aspx

http://msdn.microsoft.com/en-us/library/ms788967.aspx

Read Example using X.509

To read the carrier details, we must call the “CarrierCollection” using the Carrier ID parameter.

Refer to the code snippet below for details on how to do it from a .NET application using X.509 Certificate Authentication:

1. Use the following method for getting Carrier information from the carrierId parameter.

private static void GetCarrierByID() {

2. Specify the carrierId parameter for which we want to receive information.

string carrierId = "AA"; //American Airlines



4. Add a delegate that will execute right before the request is sent to the service. In this delegate, add the Client certificate to the outgoing request.

service.SendingRequest += (s, e) => {

string certificateSubject = "<User Certificate Subject>"; X509Certificate2 certificate = GetCertificateFromX509Store(certificateSubject); // Attach the client certificate to the request ((HttpWebRequest)e.Request).ClientCertificates.Add(certificate);

};

5. Execute the query below to the service to retrieve the carrier and save the result.

var carrier = (from Carrier c in service.CarrierCollection where c.carrid == carrierId select c).FirstOrDefault();

6. Use the result to display the information obtained.
